I played your game! Here's some quick feedback.
Firstly, I loved the intro, it was awesome

. I also liked the fact that you made it skippable. The layout of the information on screen was good too.
I couldn't actualy play it for a long time without it crashing through. When I tried to enter a different sector, it crashed. First It displayed the message saying how many fighter ships I lost, I then pressed space, crash. The second time I only had to enter the number 1 for it to crash. I had a look at the memory usage in task manager and I saw that when the game crashed, the physical memory usage spiked dramaticly. Hopefuly you'll be able to fix it.
Hmm, as for the feedback that you actualy asked for... I don't know. Personaly, I think it's already more of a game than a simulation, but some people might disagre with me.
